Hi Kathy,
Mary Kay is right, there are so many mimics of the disease and it's the Neuro's job to rule these things in, or out during a thorough workup.
Do you know what this workup consists of so far? Was the MRI of the brain only? Do you know the strength of the machine used?
What labs were run? Sorry for all the questions, but it takes so much digging, and knowing this, we can help you put together a plan for your next steps if this Dr.
